There are more then enough reading lights around, I should think. This one, the Led Ear Lite, is different from the others. Why? You mount it to your ear! It works the same as a Bluetooth headset for your mobile telephone. You turn it on, put it on your ear and it beams a light on your book. Since it is a LED it is supposed to work for 100,000 hours. You can also adjust the angle of the light. I think that is some very inventive thinking of the person who invented it. You can learn more about it here. Or, of course check Ebay first.
